' I SYRINGE.

Application filed December 8, 1921, Serial No. 520,930. Renewed J'anuarySO, 1926.

This application is a renewal of prior application filed byme December 8, 1921, Se-,

rial Number 520,930 for syringes allowed June 19, 1924, and relates more particularly to improvements in dilating vaginal syringes.

t The objects of the inventionare to provide 7 s a device of this character in which the dilating fingers may be more readily and rapidly 1 for spraying the water or other fluid; to secure simplicity of construction and operation and to obtain other advantages and results as may be brought out in the following descr1ption.

Figure 1 is a side elevation of a syringe constructed in accordance with the present invention, and showing the fingers in retracted normal position; 1

Figure 2 is a similar view of the outer end of said syringe but showing the fingers in extended or dilated position; I A 1 Figure 3 is a longitudinal sectional view of the end of the syringe showing the tip and water outlet;

Figure 4 is a transverse sectional view on line 41- 1 of Figure 2;

Figure 5 is a longitudinal sectional View of the body portion showing the fingers in normal position;

Figure 6 is a side elevation of one of said fingers removed from the body portion and in normal position; I y

Figure 7 is a cross sectional view of the same on line 7-7 of Fig. 6;

Figure 8 is a view similar to Fig. 6 but showing the finger extended.

Figure 9 is a cross-sectional view on line 9-9 of Fig. 8, and

Figure 10 is a sectional view of the metallic ring on which the rubber portion of the finger is carried for mounting the same in the body position.

In the specificembodiment of the invention illustrated in said drawings, the reference numeral 1 indicates the body of my improved syringe at one end of which is a connection 2 for introduction of water and a 'Referring to the accompanying drawing in which like numeralsol' reference indicate similar parts throughout the several'vlews;

of the device. The tip 5 is shown as screw threaded at its inner end for attachment with corresponding screwthreads in the end of the body portion, and the channel 6 communicates directly with the interior chamber 7 of said tip from which water may be sprayed through a plurality of suitable holes 8.

In the construction shown, means are provided for spraying the water in opposite directions, this constituting one of the features of the present invention. To accomplish the desired result, the cap is arranged so its edge .nextthe body portion is spaced slightly therefrom so as to provide a circumferential gap through which the water may escape. The ciroumferentialend walls bounding this gap are sloped for a'sliort portion ofthe circumference in one direction, and for a short ad acent P01111011 of the circumference they are sloped in another direction and so on alternately for the entire circumference. This alternate sloping of the walls ofthe body portion and tip gives a serrated or toothed appearance to the crevice or gap between these two parts, as clearly illustrated in Figures 1, Qand 3.

Adjacent the removable tip 5, I provide a plurality of extendible fingers 9, preferably arranged in staggered relation to each other about the body portion and arranged and adapted to be extended or dilated and retracted as occasion requires. These fingers are so constructed that in their normal position they are retracted and are only extended upon positive application of pressure within. Furthermore, the said fingers 9 are so constructed as to normally fold and occupy only. a very short deptlnthe wall of each finger doubling within itself. By this construction, the space under the finger is open so the air or other fluid pressure may act upon the entire area of the finger immediately, thus facilitating the rapid operation of thefinger. In order to remove and attach the finger in position I have shown the same as constructed with a metallic ring 10 screw threaded on its exterior, as at 11, for engagement with corresponding screw threads in the openings in the bodyportion of the device. In order to obtain a secure attachment of the rubber finger to thesaid metallic ring, the said ring preferably has a plurality of holes 12 through which the rubber may knit together.

Within the bodyof the device I preferably provide an air or fluid chamber 13 beneath the several fingers in communication therewith so that as pressure is introduced into said chamber 13it will act simultaneously upon all of the fingerstoextend the same. This air chamber 18 is entirely separated from the water channel 6, it being clearly shown in Figures 4 and 5 as positioned around said water channel but separated therefrom by an intervening tube-like wall 14. Air or other fluid pressure is introduced into said chamber 18 from the connection 3 by means of any suitable passage 15 of a size and shape sufficient for the purpose.

Attention is called to the fact that the exterior of the device is fluted, there preferablv' being a flute16 extending 10ngitudinally of the device to each of the fingers. Furthermore, the flute 16 in line with the finger closest to the end of the device extends to a position between the othertwo fingers, thus obtaining a better discharge of the fluids along the exterior of the device.

Obviously detail changes and modifications maybe made in the construction of my improved syringe, and I do not wish to be understood as restricting myself to the exact structure shown except as set forth in the following claims when construed in the light of the prior art.

Having thus described the invention, I claim 1. In a syringe,a body portion having a fluid channel, and having a fluid chamber separated from said fluid channel, extendible fingers in communication with said chamber whereby pressure in said chamber will dilate said fingers independently of the fluid pressure in said channel.

2. In a device of the character described, a finger having a base, side wall, and tip, the tip normally folding within said side wall and said side wall normally folding within the base whereby the normal length ofthe finger is substantially its minimum length.

3. A syringe comprising a fluted body portion, fingers adjacent the end of said body portion in staggered relation to each other, the outer ends of alternate flutes extending to a position between alternate fingers.

4:. In a syringe, a body portion having a fluid channel, and having a chamber separated from said fluid channel with a plurality of openings from said chamber to the exterior of the body portion, means normally retracted in said chamber and openings and extendible out of said openings laterally of said body portion by'pressure communicated within the chamber, and means for applying pressure within said chamber from a point exterior to said bodyportion and forcing said extendible means out through said openings.

In testimony whereof I affix my signature.

ISAAC WVILLIAM FRIEDMAN.
